Fun Fact
Computers cannot generate truly random numbers on their own. Most "random" numbers are actually pseudo-random, created by mathematical formulas that only appear random.
Historical Context
Random number generation has been essential since the early days of statistics and cryptography. Before computers, randomness came from dice, cards, and physical processes. Modern software tools now make random number generation instant, repeatable, and globally accessible.
